“…Another risk factor suggested by the study was environmental tobacco smoke in relation to the symptoms of cough. The effect of both exposures, ambient air pollution and passive smoking, on the development of respiratory disorders in children is well documented [3,[14][15][16][17][18][19][20][21][22][23]. Both environmental exposures are likely to promote the development of respiratory allergy and manifestation of respiratory symptoms through non-specific mechanism involving inflammation of mucous membranes in the airways [14,24].…”

In children aged 7-9 years residing in the town of Chorzow (C) and in the town of Mikolow (M), located 30 km apart (Upper Silesia, the industrial part of Poland), respiratory symptoms were ascertained according to the parental answers to WHO-Questionnaire. Mean annual concentrations of air pollutants are higher in Chorzow than in Mikolow, and recent mean values of 24 hr measurements over November 1992-January 1993 confirmed the between-town gradient (p < 0.001) for particulates (C:166 micrograms/m3); M:129 micrograms/m3), SO2 (C:153 micrograms/m3); M:92 micrograms/m3) and NO2 (C:69 micrograms/m3); M:26 micrograms/m3). In Chorzow 24.8% (n = 1,142) and in Mikolow 25.6% (n = 480) of all eligible children aged 7-9 years were examined. Both groups (C and M) were similar in terms of sex, family history of asthma and cough lasting for 3 months (C:31.6%; M:32.3%). Frequency of the following respiratory symptoms statistically significantly (p < 0.05) differed between two groups: chest wheezing (C:21.4%; M:17.1%) and attacks of asthmatic dyspnea (C:10.3%; M:6.2%). Also, the diagnosis of asthma by physician was more prevalent in Chorzow (C:3.5%; M:1.3%; p < 0.05). Logistic regression analysis showed that after controlling for family history of asthma, environmental tobacco smoke and housing condition, the place of residence (C versus M) was statistically significantly associated with attacks of asthmatic dyspnea (p < 0.05) and a "borderline' significance of this factor was found in relation to wheezing (p = 0.06) and physician-diagnosed asthma (p = 0.07). The survey provided the estimate of the prevalence of chronic respiratory symptoms in children living in the most polluted urban area of Poland. Although the design of the study precludes more specific etiologic conclusions on environmental exposures the apparently higher prevalence of symptoms in children living in a more polluted town deserves further investigation.

“…Epidemiological research evidence from different parts of the world has stressed the hazards of cigarette smoking as an important factor in the cause of respiratory symptoms in children and adults [1][2][3][4]. Passive smoking is associated with increased prevalence and severity of asthma and wheezy bronchitis in children [2-8] and increased respiratory illness and incidence of bronchitis in infants [9,10].Among the harmful effects postulated for passive smoking is an association between parental smoking and bronchial asthma, wheezing, dry cough, and other respiratory symptoms in children [11][12][13][14][15][16]. Effects of parental smoking have also been detected in schoolchildren.…”

Previous epidemiological studies have associated parental smoking with an increased incidence of lower respiratory illness and bronchial asthma. The aim of the present study was to investigate the association between parental smoking habits and diagnosed wheezy bronchitis in schoolchildren in Saudi Arabia. In a cross-sectional study 3,041 schoolchildren ages seven to 12 years were randomly selected in Dammam, Jeddah, and Riyadh; representing three different geoclimatic regions of Saudi Arabia. Standardized questionnaires were used in our study. The results showed that paternal smoking had a significant effect on the frequency of wheezing when paternal and maternal smoking were considered separately. There was no considerable variation in the parental smoking habits in three areas. The association between passive smoking and diagnosed wheezy bronchitis and frequency of wheezing attacks was. highly significant (P<0.0001). Overall, the results tend to confirm that there is a real effect of passive smoking on the respiratory health of children and that parental smoking is a risk factor for wheezy bronchitis in children. Ann Saudi Med 1993;13(3):222-225. Epidemiological research evidence from different parts of the world has stressed the hazards of cigarette smoking as an important factor in the cause of respiratory symptoms in children and adults [1][2][3][4]. Passive smoking is associated with increased prevalence and severity of asthma and wheezy bronchitis in children [2-8] and increased respiratory illness and incidence of bronchitis in infants [9,10].Among the harmful effects postulated for passive smoking is an association between parental smoking and bronchial asthma, wheezing, dry cough, and other respiratory symptoms in children [11][12][13][14][15][16]. Effects of parental smoking have also been detected in schoolchildren. The most important risk factor for the development of chronic respiratory symptoms, childhood asthma, chronic cough, and wheezing is cigarette smoking [17,18]. Studies in schoolchildren have shown a significant association between parental smoking and the risk of childhood asthma, chronic cough, occurrence of wheeze and respiratory conditions [11][12][13][14][15][16][17][18][19][20][21][22][23]. Evidence is accumulating of a relationship between parents smoking and respiratory symptoms in children [24].The aim of the present investigation was to study the association between passive smoking and diagnosed wheezy bronchitis in Saudi schoolchildren; in addition, to confirm the harmful effects of parental smoking habits on respiratory symptoms in children. Material and MethodsThe schoolchildren studied were the subjects of a cross-sectional population study conducted in three different regions: Riyadh, Dammam, and Jeddah, cities of the Kingdom of Saudi Arabia, between January 1987 and February 1989. Three regions were chosen because they represented three various geoclimatic regions of Saudi Arabia: Riyadh, which has a dry climate, is the capital of Saudi Arabia and has a population of 2.5 m...

“…All children were examined at ages 5 and 10 years. [16][17][18] Beginning in 1979, we monitored a cohort of children with atopic heredity and a cohort of control children from nonatopic families to determine the significance (or otherwise) of preventive measures in infancy in relation to atopic manifestations 9 years later. skinprick tests using eight common inhalant allergens were performed.…”

A national program for the prevention of atopy in children has been in progress in Finland since 1979. Its aim is to prevent or at least to reduce atopic symptoms in childhood. Since the start of the program we have followed a group of 119 children with and without a family history of atopy. Half the atopy-prone children kept to the diet intended to prevent atopy, i.e., breast-feeding prolonged up to age 3 months and introduction of solid food and formulae based on cow's milk after age 3 months. All children were examined at ages 5 and 10 years. In addition to clinical examination and interview. skinprick tests using eight common inhalant allergens were performed. At age 9 to 10 years, 38 of the 119 children (32%) exhibited at least one atopic illness (bronchial asthma. allergic rhinitis, allergic conjunctivitis, atopic eczema orfood allergy). Forty percent of children with family histories of atopy had atopic illness. independent of diet in infancy. The occurrence of atopic manifestations in the children of nonatopic families was 21 %. Only half the children who had atopic symptoms at age 12 months had symptoms 9 years later. Asthma. allergic rhinitis. and positive skin-prick test results at age 5 years, however, correlated well with the subsequent occurrence of respiratory allergy. Our observations indicate that the preventive measures in early infancy intended to reduce the risk of atopy had no influence on atopic manifestations 9 years later.
